I don't think partitioning provides any performance, at least not for this type of query.

Please try these (for the slow case), to see which may or may not run slow:

SELECT id FROM table WHERE created BETWEEN (date1) AND (date2) AND plug = (n);
SELECT * FROM table WHERE created BETWEEN (date1) AND (date2) AND plug = (n) LIMIT 10;

Consider filing a bug at bugs.mysql.com . If you do, please post the link to the bug in this thread.
